When sighted individuals run their fingers over the raised letters of Braille their visual centers do not show increased activity Explain these findings?

These findings suggest that the brain may have developed an ability to process tactile information separately from visual information in individuals who are proficient in reading Braille. The tactile information from the fingers is directly processed in the somatosensory cortex, which is why visual centers do not show increased activity during Braille reading for sighted individuals.
